Thiatriphyrin(2.1.1): A Core-Modified Contracted Porphyrin
Elusive in its free‐base form, the core‐modified contracted porphyrin thiatriphyrin(2.1.1) was prepared with p‐tolyl substituents by intramolecular McMurry coupling and then converted into various alkoxy‐substituted analogues (see scheme; DBU=1,8‐diazabicyclo[5.4.0]undec‐7‐ene). In the presence of t...

Summary: | Elusive in its free‐base form, the core‐modified contracted porphyrin thiatriphyrin(2.1.1) was prepared with p‐tolyl substituents by intramolecular McMurry coupling and then converted into various alkoxy‐substituted analogues (see scheme; DBU=1,8‐diazabicyclo[5.4.0]undec‐7‐ene). In the presence of trifluoroacetic acid (TFA), each of these compounds was transformed into the protonated thiatriphyrin(2.1.1), which exhibited moderate aromaticity. |
